@MomchilGorchev Thanks for this PR.

This is an advanced feature and we'd need a few things if we want to support this properly:

• Documentation - What these do, how to write one of these, what are the rules, when to use one and so on.
• Live Examples
• Tests - Node and Icon renderer are integral to proper working of the component, so it needs to have proper tests.

Let me know if you have any questions.

Hey, Im sorry for the late reply, will create docs, live examples and test and will ping you back for review!
Thanks!
